Artisan Partners Asset Management Reports Higher August Assets Under Management

04:57 PM EDT, 09/10/2026 (MT Newswires) -- Artisan Partners Asset Management (APAM) said late Thursday its preliminary assets under management in August rose to $183.5 billion, up from $183 billion in July. As of Aug. 31, Artisan Funds and Artisan Global Funds accounted for $94.5 billion of total AUM, up from $94.3 billion a month earlier. The company said it was notified in August that a long-standing sub-advisory client is diversifying its mandate from a single-manager to a multi-manager structure, with Artisan remaining one of three managers under the new structure. The change is expected to result in the rebalancing of approximately $6 billion from the Global Value strategy in September 2026. The impact on revenue is expected to be less than the corresponding reduction in AUM.
